And do you mount the flat part of transducer facing down ? Filled with silicone so no air bubbles ?

Ok I found a depth module apparently there was only 2 in Australia but managed to get one sent to Malibu here in new Zealand and I got the lowrance transponder made my own plug but it is saying depth bad status on screen and 0.0 on other screen when I had depth gauge transponder in a big bucket of water.

I am trying to do this but can’t figure out where the plug it for the depth gauge behind dash?
